Specific embodiment
To make the purpose of the present invention, technical solution and effect clearer, clear and definite, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to
Limit the present invention.
Please with reference to attached drawing 1-4.Module label in figure: contact, control module 10, manual control unit 11, position pass
Feel module 20, Current Mutual Inductance module 30, tripping coil 40, magnetic tripping module 50, trip-gear button 60, communication module 70.
Embodiment 1
The present invention provides breaker operator recognition methods, comprising steps of
S10, control module 10 receive contact position signal, the detection of Current Mutual Inductance module 30 that position sensing module 20 detects
Fault-current signal and tripping coil 40 drive contact feedback signal；
S20, control module based on the received contact position signal, fault-current signal and driving contact signal, pass through control
The reason of analytic approach processed obtains circuit breaker trip is fault trip or manual operation, and feeds back corresponding operation signal.
In the actual operation process, the contact that control module 10 only needs to receive the identification of position sensing module 20 (is not marked
Know) location information, the fault current information that Current Mutual Inductance module 30 detects and tripping coil 40 action message, so that it may
It is artificial or failure cause with accurately judge breaker, facilitates staff and accurately taken according to feedback information
Counte-rplan.E.g. manual operation, then cannot take remote control close a floodgate measure, avoid generate safety accident, in addition if it is
Failure leads to breaker open operation, then can attempt remote control closing operation, and fortune inspection personnel on site row can be arranged if unsuccessful
Except failure.
Control module 10 described herein is fed back corresponding operating signal and is not limited to server feedback, further includes using display screen
Directly scene feedback.
In further preferred embodiment, the control module 10 is connect with server, and corresponding operation signal is anti-
It is fed in the server.Such as the control module 10 is connect using the communication module 70 with the server, it is such
Benefit is that the server can judge whether the control module 10 is in and connect shape by the connection of the communication module 70
State；There is excellent effect for the accurate exclusion of failure.In preferred scheme, the communication module 70 is communication line, in others
In embodiment, WIFI or 4G connection is can be used in the communication module 70, but corresponding signal is easy to receive electromagnetic wave
Interference.
Further, the operation signal includes: manual operation, remote control operation, fault protection trip, manual control
Separating brake, trip-gear separating brake and back-up protection tripping.
Specifically, the contact is become by closing position when manual operation breaker realizes breaker open operation by handle
Change to energy storage position.It is described when the control module 10 judges route failure electric current by Current Mutual Inductance module 30
Control module 10 drives the contact to be changed to trip positions by closing position by tripping coil 40, makes circuit breaker trip.When
When remote control operates separating brake, remote control signal is sent to the control module 10, the control by the communication module 70
Module 10 drives the contact to be changed to trip positions by closing position by tripping coil 40, makes circuit breaker trip.Safeguard people
Member can send signal to tripping coil 40 by the control module 10 at the scene and the contact is driven to be changed to by closing position
Trip positions make circuit breaker trip.When transient high-current (for 16-20 times or more of general electric current) occurs, due to electric current pole
Greatly, to ensure quickly to cut off failure.Directly driving the contact from magnetic tripping module 50 at this time becomes de- from closing position
Button bit is set, while controller can detect this transient high-current signal by Current Mutual Inductance module 30.Pass through tripping examination when artificial
When testing button 60 to breaker progress sub-switching operation, operating mechanism is changed to trip positions by closing position at this time.
The recognition methods conducted in the control module 10 is referring in particular to attached drawing 2:
The working condition of S21,10 detection contact of control module, it is artificial to server feedback if working condition is energy storage
Operation signal；If working condition is tripping, S22 is thened follow the steps；
S22, the control module 10 detect whether tripping coil 40 has the driving contact action, if so, executing step
Rapid S23；If it is not, thening follow the steps S25；
S23, the control module 10 detect whether to receive the telecommand of server, if so, remote to server feedback
Journey remote control operation signal；If it is not, thening follow the steps S24；
S24, the control module 10 detect whether to receive the Fisrt fault current signal of Current Mutual Inductance module 30, if so,
Then to server feedback fault protection trip signal；If it is not, then to server feedback manual control sub-switching operation signal；
S25, the control module 10 detect whether to receive the second fault-current signal of the Current Mutual Inductance module 30, if
It is, then to server feedback back-up protection trip operation；If it is not, then to server feedback trip-gear sub-switching operation.
In specific operation process, when breaker controller by operating mechanism position sensing module 20 detect contact from
When closing position becomes energy storage position, that is, it can determine that breaker is people's work sub-switching operation.
When the control module 10 detects that the contact becomes threading off from closing position by sensing module described in position
When position, the control module 10 has further determined whether 40 drive actions of tripping coil, if having the movement, further
It discriminates whether the remote control operation issued for the communication module 70, if not remote control operation, then can pass through the Current Mutual Inductance mould
The Fisrt fault electric current of block 30 come be judged as fault protection trip act, if not error protection, then can determine that as manual operation
Controller mode carries out breaker open operation operation.If the control module 10 does not detect that the driving of tripping coil 40 is dynamic
Make, then the second fault-current signal is detected by the Current Mutual Inductance module 30, the second fault current described herein is i.e. instantaneous big
Current signal then may determine that and drive the contact for magnetic tripping module 50, carries out trip protection.Second event if it does not exist
Hinder current signal, being then determined as manual operation trip-gear button 60 makes breaker manually trip.
Embodiment 2
The present invention also provides a kind of breakers, including including control module 10, position sensing module 20, Current Mutual Inductance module
30, tripping coil 40 and contact, the position sensing module 20, the tripping coil 40 and the Current Mutual Inductance module 30 are distinguished
It is connect with the control module 10；The tripping coil 40 is for driving the contact；The position sensing module 20 is for examining
Survey the working condition of the contact；The Current Mutual Inductance module 30 is for the fault current in detection circuit.
The preferred breaker further includes magnetic tripping module 50 and trip-gear button 60, the magnetic tripping module
50 for the transient high-current and the driving contact in detection circuit；The tripping experiment button is for driving the touching
Head.
The Current Mutual Inductance module 30 can measure respectively the induced current of three-phase electricity, and be separately sent to the control mould
Block 10, can be when feeding back the operation signal, while showing fault protection trip, and feedback is that the circuit of which phase occurs
Failure, it is more accurate for debugging.
The control module is preferably MKM33 model processor.
It, can according to the technique and scheme of the present invention and its hair it is understood that for those of ordinary skills
Bright design is subject to equivalent substitution or change, and all these changes or replacement all should belong to the guarantor of appended claims of the invention
Protect range.
